Abstract: A kind of rudder control system used in UUV was introduced. The hardware structure, control method and software flow of this rudder control system were described in this paper .This control system, with DSP as MCU, angle acquisition with resolvers and using fuzzy-PID as arithmetic, make rudder achieve the aim at hight accuracy position and response characteristic.

Key words: rudder control system; UUV; servo control
